# Don't Start It: AdBlue in a Diesel Tank in Rishton

With AdBlue in your diesel tank, your ignition remains off and so does the engine.

Water with urea mixed in it: that's AdBlue.

It doesn't burn, it does not mix with diesel, and the damage it does begins when your fuel system draws it in.

A drain and a thorough flush, done where the vehicle is around Rishton, is usually all AdBlue in a diesel tank needs — if it's caught before the engine has run.

Nothing comes before ringing 0333 366 0103.

## Those opening minutes: AdBlue in the diesel tank around Rishton

Do:

- Pocket the keys, which stops someone switching the electrics on.

- If you're anywhere close to moving traffic, put the hazard lights on.

- So you can tell us which liquid it was and roughly how much, save your receipt or the empty bottle.

- The van finds you quickest with a postcode starting BB1 4, or simply the name of a street nearby, and so call from the spot.

Things not to do:

- No starting your engine — not briefly, not to shift the car.

- Don't switch the ignition on. On many diesels that alone runs the fuel pump.

- AdBlue does not dilute in diesel — it separates out — so adding extra diesel will not thin it.

- Leave the car where it is rather than driving it anywhere, even a short distance along High Street.

- By the road, do not attempt emptying it yourself.

On a forecourt in Rishton, whether it is the BP or another one, ask the staff to help you roll the vehicle clear of the petrol pump.

If you are on your own drive, leave the vehicle exactly where it stands.

## AdBlue in a diesel tank: what it does

The motor is not what AdBlue is made for; the exhaust is.

It goes into its own tank and is sprayed into the exhaust gas to fresh it.

A fuel pump isn't designed to take it, and AdBlue was never intended to travel through one.

Poured in with the diesel, it keeps separate rather than blending — quite different from fuel.

It is heavier than diesel, so it sinks and gathers at the bottom of your tank, which is where the pickup sucks fuel from.

Once your pump runs, the AdBlue is first to go through. Until then it sits beneath the diesel, and that is how a car topped up in Edge End last night and not started remains the simple case, provided no one touches your key.

From there it does two kinds of damage.

As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps running on the components it gets to for as long as it remains there.

Pipes carrying AdBlue mean damage by morning for a vehicle parked around Rishton. Only inside the tank, it stays the same.

Then there's the water: it offers no lubrication to the parts that rely on it most — the injection pump and each injector.

## AdBlue in a diesel: why it is regularly worse than petrol

Fill a diesel with petrol by mistake at the Morrisons, and the problem is diluted fuel.

It mixes with your diesel, and whilst it is inside your tank it causes no damage; the damage comes from running your motor on it.

AdBlue in a diesel is a fault of the wrong substance altogether.

Not burning, it cannot just be run through.

Crystals and corrosion stay after the following fill, and AdBlue splits back out of your diesel, and so watering it can't help. That is why the flush counts so much, and turning your key "to see" does more harm here than nearly any other mistake — in Great Harwood or the heart of Rishton alike.

With AdBlue, the good news is no separate from petrol.

If the engine has not run, the AdBlue is still in your tank, and the tank is the quickest part of a fuel system to clear, wherever across Lancashire your car is standing.

## Rishton: how AdBlue ends up in a diesel tank

Plenty of motors put the AdBlue cap alongside the diesel cap, now and then behind one flap, and after dark the two may look identical. Nobody means it.

It usually happens at home, from a container grabbed on the journey home, not at the filling station.

Usually, it occurs in one of a few familiar ways.

Halfway through the morning drop-off, the dashboard warns, and outside St Charles' Roman Catholic Primary School, a Voluntary Academy the refill is hurried.

Close to Harwood Road, a driver tips a container in at home in the evening.

Or someone new to that flap refills your car in dim light, stopped in the car park outside Rishton Workmens Club.

Hired motors, brand-new cars, company vehicles, or the second car in a home with one of each: the least known vehicles get it most.

Leave it switched off: that is the first response to an identical slip, wherever in Rishton or the remainder of Lancashire you happen to be.

## Already started your engine with AdBlue in your diesel tank in Rishton?

Then that tank is no longer where the AdBlue is.

The filter and lines have had it sucked along, and any running time carries it on to the high-pressure pump and each injector.

You may see your engine running roughly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from The Turrets Community Garden or halfway across Rishton.

When safe, stop and switch everything off — without turning it on again to see.

More of that is pulled through with each start.

If you were on the M65, under a mile from Rishton, come off at the next exit and stop somewhere sensible rather than pressing on.

Mileage counts: each mile carries the AdBlue further in, and so heading for Preston, under 15 miles away, makes a far larger job than crossing Rishton to the car park by St Peter and St Paul.

Approximately how far had it come? Tell us.

Our engineers do all of the rinsing where your car has ended up, and once the motor has been run there is more of it.

If it is noticed early, permanent damage is very uncommon.

## Emptying AdBlue in a diesel in Rishton: what it takes

Wherever it has come to rest around Rishton — a forecourt, a lay-by, a driveway, a road beside Saint James' Kirk — the van comes to your vehicle.

What was put in, about how much, and if your engine has been run: our engineers check before all else, since those decide the work.

Then that tank is cleared where the vehicle sits, and so the tainted fuel and the AdBlue come out together.

With AdBlue, more so than with petrol, flushing counts: the whole system is cleaned all the way through because what remains won't wash away by itself.

The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested.

Not run? Then expect about half an hour on site for most jobs.

The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night.

Lastly, your system is bled with clean diesel.

At that point our technicians start the car and you set off, whether from a parking space by the nearest station or a driveway around Rishton.

The check before our engineers head off is that it runs correctly on fresh diesel.

The entire job is done where the car is, so it never needs to be taken to a workshop.

At the end, there is the paperwork for the insurer: a VAT invoice plus a report from the engineer.

Rishton lies approximately 11.5 miles from Preston and 183.3 miles from London, making it a commuter town with access to larger cities.

## Rishton and Lancashire: AdBlue drains across the area

Over the BB postcode area, the vans taking AdBlue jobs around Rishton serve much of Lancashire as well, Norden, Tottleworth and Waverledge included.

Close to a border, or anywhere tricky to explain? Checking is better than guessing, so ring.

Wherever your car sits — your driveway at home, a side street, a parking area, a forecourt — our engineers empty it on the spot, with no need to bring it to us; which suits Rishton, a riverside town, well.

## What does AdBlue in a diesel tank cost to sort out around Rishton?

Every job differs, and so not one single price would be honest.

What changes the cost is, firstly, whether the engine has run and for how long; then how much AdBlue got in; and after that where the vehicle is and whether a technician can reach it safely, which is simpler on an open drive than in a tight spot behind Towngate Cafe.

Before a quote, never after, each enquiry from Rishton begins with three questions: the fuel, the amount, plus if the engine ran.

Once they are answered, a range turns into one fixed figure.

The quote is quoted on the call, before a van sets off; settling up happens on the day, by card or over the phone, with nothing upfront.

Many insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.

## Still next to the vehicle in Rishton?

Then the most useful thing you can do is nothing to the vehicle.

Ignition off, motor off, keys out.

Phone 0333 366 0103 then tell us it's AdBlue, about how much, and whether it's run. Petrol in Diesel takes it from there, around Rishton or anywhere in Lancashire.
